AUTOMATIC COUNTER AND 5T0]? DEVICE Filed Nov. 24. 1926 2 Sheets-She et 2INVENTOR WMW ATTORNEY Patented Mar. .4, 1930 ,UNITED STATES PATENTOFFICE PAUL REISS, OF BROOKLYN, NEW YORK, ASSIGNOR TO VIKING TOOLAISI'ID MACHINE 00., ING.,-O'.F BROOKLYN, NEW YORK, A CORPORATION OF NEWYORK AUTOMATIC COUNTER AND STOP DEVICE Application filed November 24,1926. Serial No. 150,585.

My invention relates to automatic counters and stop devices intended tobe installed on machines where a predetermined number of operations areto be performed and then the machine automatically stopped and it is myobject to produce a device which can be set for any desired number ofoperations in advance and which will, at the end of the number set for,automatically stop the machine, giving, if desired, an advance warningsignal that completion is at hand. The device is particularly adaptedfor attachment to machines for winding electric coils but may be usedwith machines for other purposes.

In the drawing I have shownone embodiment of my device in which Fig. 1is a front view of the device; Fig. 2 a front view of the structure ofFig. 1 with the top dial removed; Fig. 3 a view of the frame andclutching and declutching mechanism used in mitiall setting the device;Fig. 4 a side view of t e structure of Fig. 3; Fig. 5 a view partly incross section of the device; Fig. 6 a detail view of the spring stop;and Fig. 7 a detail view of the stop and alarm mechanism.

The device falls into three groups of mechanism. First, the clutchingand declutching mechanism which enables the dials to be engaged with anddisengaged from the driving means for the purpose of setting the counterSecond, the alarm mechanism which indicates the end of the operation isbeing approached and the stop mechanism which automatically stops themachine to which the device is attached. Third,thecounting mechanismwhich may be set to give an alarm and stop the machine to which it isattached at the end of any predetermined number of operations. a

The clutching and declutching mechanism comprises a frame 1 in which adrive worm 2 is mounted. An arm 3 with a finger piece 4 is pivoted onthe frame at 5 and has a pin 6 thereon. It also carries a pointer 7 atthe upper end which can be swung up and out of the way in removingthe'dials and a wire uide 8. It also carries a stud 9 in the center 'neof the worm on which the counting dials are centered. A second arm 10with a finger piece 11 is pivoted to the frame at 12 and has a notch 13adapted to engage the pin 6 on the arm 3. A spring 14 connects the twoarms 3 and 10 and serves to hold the pin and notch in engagement. Whenthe finger piece 11 is pushed down, as shown in dotted lines in Fig. 3to disengage the notch 13 and pin 6 the spring 14 will cause the arm 3to swing into the position shown in dotted lines in the same figureuntil it hits the stop 15 on the frame 1 causing the stud 9 to rise andcarrying with it the counting dials centered thereon and disengage themfrom the worm. A push on the finger piece 4 will cause the arm 3 to comedown until the notch 13 engages the pin 6 carrying the stud 9 downwardto enable the dials to re-engage the worm. By this mechanismthe counterproper may be disengaged from its drive for setting and re-engagedtherewith for operation.

The alarm and stop mechanism is shown in detail in Fig. 7 and comprisesa plate with a center hole 21 with a bearing sleeve 53 extendingtherefrom. This plate has a pointer 22 pro ecting from one edge andcarries elec-' tric connections 23 and 24, a plug 25 being provided tocarry the wires and make connection, the wire being passed out throughthe guide 8. The plate carries two dogs 26 and 27 pivoted thereon. Thedog 26 has a spring 28 extending from it to the connection 24 with acontact point 29 thereon, while the other connection 23 has a contactpoint 30 thereon. The spring 28 normally holds the contact open but onswinging the dog 26 the contacts are closed and current to actuate thestop on the machine to which the counter is attached will flow. Theother dog 27 has a spring hammer 31 adapted to ring a bell 32 asan alarmwarning that the machine is about to stop. 1

The counting mechanism comprises two dials and 41. The upper dial 41 iscut out at 42 so that a portion of the lower dial 40 is exposed and hasa pointer 43in the lower edge of the opening. Directly oppo site thepointer 43 is a notched pin 44 slidable through the dial which isnormally held up by a spring 45 and-which spring has an inwardlyextending lip 46 at its ee end.

In the device shown in the drawing the dial 41 is graduated on the outerrow clockwise from 0 to 100 and represents totals. The inner graduationsare anti-clockwise from 0 to 100 and are used for initial setting. Thepin 44 is at 0 while the pointer is at 50, which are common points onboth scales. This dial 41 has 100 teeth on its out-er edge which engagethe worm 2. This dial is used in setting the machine to count anydesired number from 1 to 100.

The lower dial 40 has a circular groove 50 near its edge with a cut ring51 revolvable therein. This cut ring has a vertical end at 52 and abevelled end at 53. A clamp piece 54 with a pointer 55 thereon serves tolock the ring to the dial 40-at any desired point, the pointer 55thereon being located opposite the open ends of the ring 51. In thedevice shown in the drawing this dial 40 is graduated clockwise from 0to 9,900, each graduation representing 100 turns of the worm 2 as willbe later explained. The dial 40 has 99 teeth, 47 on its edge whichengage the worm 2.

The dials 40 and 41 revolve independently on the sleeve 53*, the alarmand stop mechanism being mounted on shaft 9 and the arm 3 and heldagainst movement. This is accomplished b slipping the dials over thesleeve 53 an then slipping the alarm and stop mechanism, with the dialsthereon, over the stud 9 and drawing down on the thumb nut 55 whichengages the threaded end of the stud and locks the sleeve and stomechanism Fig. 5, to the arm 3 while leaving the dials free to revolve.In this way the dials, when disengaged from the worm, may be freelyrevolved for setting and when engaged with the worm will beindependently driven. By loosening the thumb nut 55 the pointer 22 maybe moved to any desired position and then locked to the arm 3.

As an illustration of a use of the device I will describe its operationin conjunction with a coil winding machine in which a number of turns ofwire are to be wound on a spool or mandrel. The worm is directlyconnected to the end of a shaft carrying the spool or mandrel (notshown) so that the worm revolves at the same speed as the shaft. Thefinger piece 11 is pushed to release the arm 3 and carry the dials outof engagement with the worm. If any number of turns between 1 and 100are to be wound the alarm and stop mechanism are removed and the upperdial 41 lifted off. The cut ring 51 is moved until the pointer 55 is at0 on the scale when the ring and the dial 40 will revolve as a unit. Thedial 40 is slipped on the sleeve over the dial 41. The dial 41 is thenrevolved until the 0 is in line with pointer 7, pointer 43 in line with0 on 40 concealing 55". The finger piece 4 is then pushed to engage theteeth on the edges on the dials 40 and 41 with the worm 2. Should theact of setting move the 0 of dial 41 off the pointer 7 it may bereturned to 0 by a few turns of crank C. The alarm and stop mechanism isthen revolved until the pointer 22 alines with the figure representingthe number of turns desired (say 73) on the inner line of graduations on41 when the clamp nut 55 is set down to clamp the alarm and stop deviceto the arm 3 and hold it against movement.

The end of the wire to be wound is then attached to the spool or mandreland the machine started, the dials will revolve until the pin 44, whichis shown, due to the lip 46 on the spring 45 being in the cut 52 in thering 51, strikes the dog 27 when the bell will ring and a few turnslater and at the desired number of turns (73) the dog 26 will strike thepin closing the contact and allowing current to flow to actuate themachine stopping means (not shown).

To reset the device to wind the next coil the dials are disengaged fromthe worm and returned to 0 with respect to the pointers 7 and 43,reengaged with the worm when the device will run until the desirednumber of turns have been wound when it will first sound the alarm andthen stop the coil winding machine. As a check to show that the desirednumber of turns have been actually wound the pointer 7 will be oppositethe number on the outer scale of graduations on the dial 41 at the endof the operation.

If it is desired to wind a number of turns in excess of 100 (say 9473)the cut ring 51 is loosened and the pointer 55 set opposite the 9400graduation on the dial 40 and there locked. The dial 41 is revolveduntil the 0 is opposite the pointer 7 and 0 on the lower dial 40 untilin line with the pointer 43. The dials and worm are engaged as before.The pointer 22 on the alarm and stop mechanism is set opposite the 73 onthe inner line of graduations on the dial 41 and clamped in place by thethumb nut 55, and the machine to be controlled started. The pin 44 willbe out, due to the lip 46 on the spring 45 riding the ring so that thenotch cut out in pin 44 is in line with the travel of the dogs 26 and27. At the end of one hundred revolutions the dogs 26 and 27 will havepassed through the notch in the pin 44 but the dial 40 will have gainedone tooth on the dial 41 since it has one less tooth than the dial 41.This passing action will recur until the 9400th turn of the worm whenthe pressing action of 45 will drop lip 46 into the cut 52 in the ring51 and the notch in the pin 44 attached to 45 will drop below the pathof travel of the dogs 26 and 27 ready to strike them on the next revolution of 40 and 41. On the 73rd turn of the worm thereafter the dogswill strike the pin and sound the alarm and stop the machine. Theinclined portion 53 of the cut or groove 52 in the ring 51 causes thelip 46 to ride out of the cut on each revolution of the dial 40 untilthe latter has gained the required distance on 40, when 46 is thendropped into the groove to stop further movement of the dials. As acheck to show that the 9473 turns have been made the dial 40 will stopwith the pointer 43 against the 9400 graduation in the dial 40 and thepointer 7 will be opposite the outer graduation 73 on the dial 41.

In like manner the device may be set for any desired number of turns andthe operation repeated indefinitely by simply disengaging the dials fromthe worm and returning them to 0 and reengaging the worm.

If the inertia of the machine to which the device is attached is suchthat it is carried, say ten turns, after the stop mechanism operates thedevice is, set ten turns short on the dial 41 so that the desired numberof turns will always be made by the time the machine stops.

Devices other than electric ones may be substituted as stop mechanismsand the alarm bell may be omitted and other alarms substituted thereforwithout departing from my invention. I
